Known issues and quirks

  • The power switch is an open design which tends to get dirty and corrode; this can cause graphical glitches or other issues when the system is switched on. Cleaning the switch thoroughly using contact cleaner will usually resolve this problem, although it is not a permanent fix.
  • The 74LS541 logic chips for the controllers are highly susceptible to failure due to static discharges, and are typically the cause of issues such as unresponsive controllers or a joystick direction being held down when it isn't. Replacing these chips will usually fix these problems.
  • The AC adapter is a poor, sealed-up design which can damage the ColecoVision if it is faulty.
